Ground Water Quantity and Quality Management: Agricultural Production and Aquifer Salinization
over Long Time Scales
Provedor de dados: 31
Autores: Knapp,
Keith C.; Baerenklau,
Kenneth A.
An economic model of ground water salinization is developed. Starting from a full, high-quality aquifer, there is an initial
extraction period, an intermediate waste disposal period, and a final drainage period. Drainage management is initially source
control and reuse, but eventually culminates in evaporation basins and a system steady-state. This process occurs over long time
scales but is consistent with historical observation. Efficiency is qualitatively similar to common property though quantitative
magnitudes differ substantially. Regulatory pricing instruments are developed to support the efficient allocation. The system is not
sustainable in that net returns generally decline through time until the steady-state.

IMPROVING IRRIGATION WATER ALLOCATION EFFICIENCY USING ALTERNATIVE
POLICY OPTIONS IN EGYPT
Provedor de dados: 31
Autores: He,
Lixia; Tyner,
Wallace E.; Siam,
Gamal.
This study provides an empirical perspective on alternative irrigation policies for allocating limited water to agricultural
production in Egypt. Positive mathematical programming is used for model calibration. Three policy options for Egypt are tested:
water pricing, water complementary input factor taxes, and output taxes. The results of the research show that: 1) water pricing
needs to be much higher than the recovery cost in order to be effective in limiting irrigation water use; 2) at a higher tax rate,
fertilizer and energy taxes are effective in reducing the irrigation water demand while maintaining adequate welfare levels; 3) a
pesticide tax is less effective than fertilizer or energy taxes; and 4) an output tax on sugar cane and rice would...

Inflationary Effect of Oil-Price Shocks in an Imperfect Market: A Partial Transmission Input-output
Analysis
Provedor de dados: 31
Autores: Wu,
Libo; Li,
Jing; Zhang,
ZhongXiang.
This paper aims to examine the impacts of oil-price shocks on Chinaâs price levels. To that end, we develop a partial transmission
input-output model that captures the uniqueness of the Chinese market. We hypothesize and simulate price control, market factors
and technology substitution - the three main factors that restrict the functioning of a price pass-through mechanism during
oil-price shocks. Using the models of both China and the U.S., we separate the impact of price control from those of other factors
leading to Chinaâs price stickiness under oil-price shocks. The results show a sharp contrast between China and the U.S., with
price control in China significantly preventing oil-price shocks from spreading into its domestic inflation, especially in...
